A method and apparatus for optimizing scheduling of a block of program instructions to remove a condition resolving instruction from the critical path where the resolution of a condition controls the selection between input results, generated by predecessor operations, by a merge operation which passes the selected result to a successor operation. In a preferred embodiment, the successor operation is "unzipped" by duplicating the successor operations, providing predecessor results directly to the, duplicated successor operations, and scheduling the duplicated successor operations prior to the merge.
